It is best to install solar panels in the direction where the sun is strongest. The ideal tilt angle is to make the annual power output of the solar street light panel as large as possible and reduce the difference in power output between winter and summer as much as possible.
Generally, the local latitude or local latitude plus a few degrees is used as the inclination angle of the local installation of the solar cell module (generally, the inclination angle in the area south of the Yangtze River is 30 degrees, and the inclination angle in the area north of the Yangtze River is 30 degrees).
Of course, it would be best to use computer-aided design software to optimize the solar tilt angle calculation so that both can be taken into account. This is particularly important for high latitude areas. There is a very large ddifference in horizontal solar radiation between winter and summer at high latitudes.
Detailed information
Solar power generation methods There are two solar power generation methods, one is light conversion method -heat-electricity and the other is light-heat-electricity conversion method.
(1) The light-heat-electricity conversion method uses thermal energy generated by solar radiation to produce electricity. Generally, a solar collector converts the absorbed thermal energy into steam as the working fluid and then drives it away. a steam turbine to produce electricity. The first process is a light-heat conversion process; the second process is a heat-to-electricity conversion process.
(2) The method of directly converting light into electricity uses the photoelectric effect to directly convert the energy of the raysolar energy generation into electrical energy. The basic device for converting light into electricity is the solar cell.
A solar cell is a device that directly converts solar energy into electrical energy through the photovoltaic effect. When the sun shines on the photodiode, the photodiode converts solar energy into electricity. . Light energy is transformed into electrical energy, creating an electric current.
When many batteries are connected in series or parallel, they can become a solar cell array with relatively large output power.

What is the best tilt angle for solar panels
Direction: hemisphere south faces north,
strong>Northern HemisphereThe best direction is south. Angle: 9 degrees - latitude.The angle of inclination of the panel isintended to allow the sun to receive as much energy as possible, and the size of the tilt angle is related to your latitude. Because the Earth's axis of rotation and orbit are not perpendicular. The angle of the sun is different in different seasons, with a difference of ±23 or 4 degrees. The midpoint angle of the sun occurs at the spring and autumn equinoxes. On this day, at noon, the angle of the sun is exactly 9 degrees – your latitude. Through comprehensive calculations, the optimal tilt angle for a year should be a little larger than your latitude to achieve the maximum value received throughout the year.
Calculated based on the latitude and season of your geographic location. Assuming your latitude is X degrees north latitude, the tilt angle is between summer solstice X- 23°26' and winter solstice X +23°26'. If it needs to be corrected, it is more appropriate to take the average valueX degrees.
